Complex parameter use

Question

Hi,
I'm a newbie to PL/SQL development as well as odp.net.
I need to bind data from stored procedures via parameteres, that has some really complex structure. E.g.:
procedure GetDeliveryNoteList(
PIN in GetDeliveryNoteList_IN,
POUT in out TAB_GetDeliveryNoteList_OUT
type WPSADM.GETDELIVERYNOTELIST_IN as object(
CUSTOMER_ID varchar2(255),
DOC_COUNT number,
DOC_NUM varchar2(255),
DATE_1 date,
DATE_2 date,
ORDER_ID number
type WPSADM.TAB_GETDELIVERYNOTELIST_OUT as table of TypeGetDeliveryNoteList_OUT;
type WPSADM.TYPEGETDELIVERYNOTELIST_OUT as object(
DOC_KEY number,
DOC_NUM varchar2(255),
DOC_DATE date,
DOC_SALE_PRICE number,
COMPLAINT_INFO varchar2(255),
ARCH_KEY number,
ARCH_DESC varchar2(255),
ARCH_NAME varchar2(255),
ARCH_MIME varchar2(255),
KOD_LEK varchar2(6),
NAZEV_LEK varchar2(30),
CISLO_OBJ varchar2(255)
The question is, how do I create such a parameters. I can get data, using simple params like varchar2:
OracleParameter parm = new OracleParameter();
parm.OracleDbType = OracleDbType.Varchar2;
parm.Value = TextBox1.Text;
parm.Direction = ParameterDirection.Input;
cmd.Parameters.Add(parm);
OracleParameter parm_out = new OracleParameter();
parm_out.OracleDbType = OracleDbType.Varchar2;
parm_out.Size = 1000;
parm_out.Direction = ParameterDirection.Output;
cmd.Parameters.Add(parm_out);
cmd.CommandText = "INFO.INVOICES.JK_echo_par";
cmd.CommandType = CommandType.StoredProcedure;
OracleDataReader dr = cmd.ExecuteReader();
dr.Read();
label1.Text = parm_out.Value.ToString();
But the Oracle Type is much more complex.
Any suggestions?
TIA, JiKra
